Abstract

An ignition distributor is arranged so that its axis is aligned with the central longitudinal axis of a camshaft. A generally cylindrical cam is attached to an end of the camshaft for driving a rotor of the ignition distributor. A flange on the cam extends transversely to the central longitudinal axis of the camshaft and is aligned with an extension of the rotor. Screws are provided to connect the flange and the extension. The screws extend in parallel to the longitudinal central axis of the camshaft and are distributed around the flange to balance the distribution of mass around the central axis. The cylindrical cam fits within an opening in a housing which is only slightly larger than the outside diameter of the cam to reduce the entry of dust into the distributor.
